I've had this game for a few weeks and I really love it. There are opponents that are and easy and hard. The harder oppoments give a very good game and I have beaten them only once so far. They I'm not sure why people are complaining though as although the game uses uncommon words, they are still English words. I think people need to check their dictionary more often. Timed gamed and playing a friend using a second DS makes it more enjoyable.
